Delay - the Five D's of Prepper
Security

Actual security countermeasures can be quite complex,
but they generally conform to the five principles of
Prepper Security. The first three principles are
to Deter, Deny, then Detect. The fourth "D" is Delay.

When your physical barriers or
security forces cannot stop an attack, they should at
least be positioned to delay the approach. Additional
barriers allows your security forces the time to
regroup, reassess and reengage the approaching attack.

An effective delaying tactic will
allow for reinforcements of your perimeter security
forces. These posts will help.
